4 reasons to try Clarity

1. Energy, without the jitters or crash
Traditional stimulants leave you wired, then wiped. Clarity delivers smooth, steady energy and focus—without the jitters or mid-day crash.

2. Rewire your brain

Clarity supports acetylcholine, dopamine, and serotonin—key neurotransmitters for learning, memory, and flow states—helping you think faster and stay sharp.

3. Ingredient dosages that
actually work

No underdosed ingredients or mystery fillers here. Every ingredient is clinically dosed for real results and third-party tested for purity—something most brands don’t do.

4. Support your brain's health, now and in the long run

Clarity contains neuroprotective ingredients like Lion’s Mane, shown to boost Nerve Growth Factor (NGF), supporting brain cell growth and long-term cognitive health.

†These claims are based on a previous version of the Clarity formula. The data comes from an open-label consumer perception survey conducted in September 2024, which included at least 84 customers who had been using that version for 60 days or more. Participants received a $10 rebate for sharing their feedback. The previous formula included Lion’s Mane, Epicatechin, Alpha GPC, 7,8-DHF, and optionally caffeine and L-theanine. The formula has since been updated. A new study evaluating the current formula is planned, and updated claims are expected by August 2025.
